Grey hound sketch request - upgrade

It's day 20 of "at least one post a day" challenge, finished another request for gray hounds. Thank you for the continuous support through all of it, I hope I can continue the challenge after this month finishes.

If you wish to recreate I suggest:
• using a thin paper that isn't high quality if you're a beginner
• art is about practice and making mistakes so don't be afraid of throwing out a few papers
• using a pencil that's on the harder side like most commonly used HB and using softer ones for details like B2
• references help understand how an object (in this case animal) presents itself, maintains balance etc.
• the greyhound is built for speed with a streamlined, muscular body.
• the neck and head are long.
• their characteristic rose ears are usually folded flat against the neck when the dog is relaxed, but prick forward and may even stand somewhat erect when the greyhound is at attention.
• the loin is slightly arched, the chest is deep, and the waist is narrow, giving the dog a distinctive appearance.
